Even an electric/induction stove will generate a lot of indoor air pollution if not well ventilated. In my current London flat (which I'm moving out of soon), nobody uses the fan above the stove because it's super loud and doesn't work properly anyway. Frying pretty much anything in the kitchen will cause my PM2.5 meter, which is upstairs in my bedroom on the other side of the house, to go crazy. Often up into the hundreds of µg/m³. Good kitchen ventilation is super important, gas stove or otherwise!
